How UV and IR flame detectors work, where they suit fast-flaming fire risks, their false-alarm sources, and what to check — for UK fire alarm engineers.

Optical chambers accumulate dust, insects, steam residue and decorating debris; the analogue value creeps up until the panel flags contamination or pre-alarm. Check the environment first — a detector near an air-handling vent or in a workshop will foul repeatedly no matter how often it's swapped. Clean or replace per the manufacturer's guidance (many heads are exchange-only), record the analogue values before and after, and note repeat offenders: a location that fouls every few months needs a detection-type review, not another clean. Standards are referenced for orientation only — always confirm requirements against the current edition of the applicable standard, the site's fire strategy and manufacturer documentation.

A detector responding to the optical signature of flame (IR and/or UV), used for fast-developing fuel fires where smoke detection is too slow.

A detector combining sensing principles (typically optical and heat) to improve discrimination between real fire signatures and nuisance sources.

A point detector sensing light scattered by smoke particles in its chamber; effective on smouldering fires, more prone to dust and steam nuisance alarms.

An optical detector projecting a beam across a large space, signalling when smoke obscures it; alignment and building movement are its main maintenance issues.

A detector operating on fixed temperature, rate of temperature rise, or both; used where smoke detection would false-alarm, at the cost of slower response.

A passive infrared movement detector; siting, mounting height and environment (heat sources, pets, draughts) determine its reliability.
